Network Jitter Level Determines how jitter buffer size is adjusted by the ATA. Jitter
buffer size is adjusted dynamically. The minimum jitter buffer size
is 30 milliseconds or (10 milliseconds + current RTP frame size),
whichever is larger, for all jitter level settings. However, the
starting jitter buffer size value is larger for higher jitter levels. This
setting controls the rate at which the jitter buffer size is adjusted to
reach the minimum. Select the appropriate setting: low, medium,
high, very high, or extremely high.
Default setting: high
